A digital delay generator (also known as digital-to-time converter) is a piece of electronic test equipment that provides precise delays for triggering, syncing, delaying and gating events. These generators are used in many types of experiments, controls and processes where electronic timing of a single event or multiple events to a common timing reference is needed. The digital delay generator may initiate a sequence of events or be triggered by an event. What differentiates it from ordinary electronic timing is the synchronicity of its outputs to each other and to the initiating event.

The digital delay generator may initiate a sequence of events or be triggered by an event. What differentiates it from ordinary electronic timing is the synchronicity of its outputs to each other and to the initiating event. A time-to-digital converter does the inverse function. The digital delay generator is similar to a pulse generator in function but the timing resolution is much finer and the delay and width jitter much less. Some manufacturers, calling their units 'digital delay and pulse generators', have added independent amplitude polarity and level control to each of their outputs in addition to both delay and width control. Now each channel provides its own delay, width and amplitude control, with the triggering synchronized to an external source or internal rep rate generator - like a general-purpose pulse generator.
